In Deep: The Art and Science of DFM with Gary Ferrari


Reading time ( words)

When the topic of DFM techniques came up, I knew I had to talk with Gary Ferrari of FTG Corp. Gary has been involved with designing and manufacturing PCBs for decades, and he’s the past co-founder and executive director of the IPC Designers Council. I caught up with Gary between Thanksgiving and Christmas, and we conducted the following interview.

 

Andy Shaughnessy: Give us a quick background on yourself and your role at FTG.

Gary Ferrari: I have been in this industry for more than 50 years. The major portion of this time has been spent in PCB design and manufacturing. I have spent some time in assembly, industrial robotics, and nuclear and fossil power plant controls systems design.

I serve as the Director – Technical Support for FTG Circuits. My main function has many facets. First is to work with our customer base during the design phase of their products. I help them design for manufacture, which includes fabrication, assembly, repair, reliability, and field service. This includes end-product performance, both electrically and mechanically. It sounds like a lot, and it is. To meet today’s advanced products within short design cycles, one must consider all these areas when selecting materials, components, etc.

Second is to represent them within the standards develop committees of IPC. Many current-day issues are discussed during the development meetings, which affect both our company and our industry. There are so many new, advanced technologies cropping up constantly. One must stay on top of them if one expects to survive in this industry.

I also provide IPC designer certification through EPTAC, an IPC licensed training center. These courses are quite extensive, exposing the attendees to many of the issues affecting successful designs.

Shaughnessy:  So, what can PCB designers do to make the fabrication process go smoother?

Ferrari: The most important item that a designer can do is to talk to their fabrication and assembly suppliers. Ask them about how your design practices are affecting their ability to manufacture with low yields and high reliability. Most important is to find out the areas that are the most troublesome. The designer has many ways to attack a given issue, and may be able to select a design solution that is easier to manufacture, resulting in higher reliability and lower cost. This is most important when doing a new design utilizing a technology that is new to the company. Most fabricators can draw from experiences gained through a wide variety of technologies they have worked with through a large customer base.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

01/20/2023 | Andy Shaughnessy, Design007 Magazine
We’re in the middle of show season, and it certainly “shows.” Thank you very much. I’m here all week. Don’t forget to tip your wait staff. This week, we published a variety of articles, columns, and news items, and much of it centered on trade shows. Technical Editor Dan Feinberg brings us a report from CES 2023. IPC announced the winners of the Best Technical Paper awards for IPC APEX EXPO 2023. And we have an interview with Altium’s Rea Callender about the company’s educational efforts at APEX and around the globe.

Altium Focuses on Design Education

01/16/2023 | I-Connect007 Editorial Team
Altium keeps its eyes on the designers of the future. The company has been working with colleges and universities for years, providing free seats of Altium Designer for the next generation of PCB designers and design engineers. At IPC APEX EXPO 2023, Altium will be providing software for the finalists in the IPC Design Competition just as it did last year. They offer a variety of other educational programs as well, including Upverter classes and a design competition that aims to address environmental change. Here, Rea Callender, Altium’s VP of education, discusses its educational programs and plans for the week of the show.

The Battle of the Boards

01/12/2023 | Patrick Crawford, IPC
Last year, IPC held its first-ever design competition at IPC APEX EXPO in San Diego. PCB designers from around the world competed in a series of heats during the months before the show, culminating in a showdown on the show floor between the top three finalists. Rafal Przeslawski, now with AMD, took home the top prize last year. This year, the competition is back for its sophomore year. I asked Patrick Crawford, manager of design standards and related programs for IPC, to “layout” the details on the design contest, including lessons learned in 2022 and what’s new for the 2023 competition.
